Where should you go in Taiwan in september when it comes to the weather?
Remember:
The climate in Taiwan in september ranges from good to tolerable depending on the region and city.
Good news: It is not perfect, however, the weather in Taiwan that month is, according to seasonal norms, good in Taichung, Keelung, Taipei, Yangmingshan National Park and Sanyi. I allows to appreciate tour in these locations. And even why not take a little time to lazing in the sun!
If you do not go for the sun or the beach, but, for example to go sightseeing around, the cities of Hsinchu, Jiaoxi, Kaohsiung, Tainan, Taroko National Park, Sun Moon Lake, Yilan, Chiayi, Puli (Nantou), Alishan National Scenic Area, Kenting National Park and Hualien City have a decent enough weather for this kind of activity in september. Eventually, we advise you to avoid you get to Lanyu, Green Island (Lutao) and Taitung that month because the climate is rather bad.
